Description

V-COIL Wire thread insert Free running type S M 12 x 1.25 - 1.0 D (100 pcs.)

This product supports thread repair with wire thread inserts, which is common in maintenance and rework when an internal thread fails. You prepare the hole, cut the STI thread, then install the insert to restore the thread function.

Metric ISO identifies ISO metric threads defined by the M designation and used across general engineering.

Application

Restore damaged internal threads so you can reuse housings and components instead of scrapping them.
Use the insert system in maintenance, service repair, and small batch rework when thread engagement must be reliable.
Follow the correct preparation sequence so the insert seats without cross-threading or distortion.
Process: manual driving or assisted driving depending on your holder and machine setup
Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Use the correct installation sequence for the insert type named in the product name and keep the prepared thread free of burrs.

Benefits

Restores thread function in worn or stripped housings without oversize fasteners.
Spreads load over the thread flanks and can improve wear resistance versus a damaged base thread.
Useful for repeated assembly cycles in service and maintenance applications.
Enables standardized repair workflows when you use inserts to DIN 8140 where specified.

Drawbacks

Requires drilling and tapping to the insert system specification before installation.
Not suitable for rapid cycle production repairs where downtime must be minimal.

Step by step

Assess the damaged thread and confirm that the repair system named in the product fits the base material and wall thickness.
Drill out the damaged thread to the required preparation diameter for the insert system you use.
Cut the STI thread with the matching STI tap and keep the tool aligned to the bore axis.
Clean the prepared thread and remove chips so the insert seats without distortion.
Install the insert with a suitable installation tool and stop when the insert sits at the required depth.
If applicable for the insert type, remove the drive feature according to your process standard.
Verify the repaired thread with a fastener or gauge before returning the part to service.
